Question

Two positive point charges have a magnitude of 3.4 nC each. If the electrostatic force between the charges has a magnitude of 0.060 N, what is the separation distance?

Answer 1

Simply applying the Coulomb's law to find the distance between the two charges applying,

`F=k(Q_1Q_2)/r^2`

Given, `Q_1=Q_2=3.4*10^-9 C`

And, `F=0.60N`

so, `r=0.0012m`
